Timing a 5.7 Vortec

I have a 1997 GMC 2500 4x4. I had to replace the Distributor in it and now have the corellation code. I was pretty sure I put the Distributor back in the same place but apparently not. Can anyone give me the correct installation steps for retiming the distributor. What I have read so far says the rotor will be almost pointing at the #2 cylinder on the cap when the distributor sinks in. Is this correct or do I have some bad info.
